Ultra-Low Oxygen Measurements in Pipes
Oxygen Exchange Window OEW-PSt9
The oxygen exchange window with sensor type PSt9 is integrated in a metal flow-through connector FTM-PSt9. With the exchange window a used sensor coating inside the FTM can easily be replaced. The PSt9 type sensor allows monitoring ultra-low oxygen concentrations of 0 - 200 ppmv oxygen in gases.
- Contactless measurements down to 0.5 ppmv oxygen
- No consumption of oxygen
- Long-term stability
